I considered making this an article, but this seemed to be the better way to do this.
The intro image shows a USB microscope (~$30.00) and one of the pictures it took. It is especially interesting because I didn't really think this would be of much use. I just liked the idea of it. I had the "toy" sitting in my office for only 4 days before I really needed to use it. One of my users came to me with a MacBook Pro that no longer started, at all. Under normal circumstances, meaning if it was a windows based computer, I would take it apart and see what the problem was. There was a problem with that. Since it was a MAC computer, I didn't have the correct wrench to unscrew the chassis. I took my USB microscope, pictured above, and took a picture of the screw hole, also pictured, which I then sent out to my colleagues within the institution (a medical college) to see if anyone had a screwdriver to fit this screw.
It took about 2 hours before I received a response that someone indeed did have the correct tool and would either be willing to lend it to me or do the job themselves.
